The Christopher A. Dorrance collection consists primarily of original autographs of important and/or famous people of the United States of America from its founding to the early 21st century. The subjects of the autographs include presidents and first ladies, government officials, political and military figures, musicians, authors, actresses and actors, athletes, reformers and civil rights era activists, foreign leaders and celebrities, flyers and people associated with aviation and aeronautics, etc. The autographs in this collection are written on various mediums including, framed posters, official documents, photographs, books, cards, letters, and various forms of paper ephemera. The series titles reflect what the donor prescribed to his collection. The one change made at the discretion of the archivist was to change the word "foreign" to "international." The signatures were originally housed in three ring binders. The order established by the donor has been maintained. Several signatures are part of larger manuscript pieces, such as letters or ephemeral items such as programs.
